Notes
* 2. All voltages are with respect to ground. VSS1-4 must be connected to the same ground.
* 3. The maximum analog input voltage is smaller value between (AVDD+0.3)V and 4.3V.
* 4. The maximum digital input voltage of SDIN1, SDIN2, SDIN3/JX2, LRCK1, BICK1, LRCK2, BICK2,
LRCK3/JX0/SDIN4, BICK3/JX1, PDN, SCL/SCLK, CAD/CSN, SI a、nd TESTI pins is smaller value
between (TVDD+0.3)V and 4.3V.
* 5. The maximum digital input voltage of XTI pin is smaller value between (VDD33+0.3)V and 4.3V.
WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal
operation is not guaranteed at these extremes. 7. Recommended Operating Conditions

Notes
* 6. The power-up sequence with AVDD, DVDD, TVDD and VDD33 is not critical. The PDN pin should
be held “L” when power is supplied. The PDN pin is allowed to be “H” after all power supplies are
applied and settled.
* 7. Do not turn off the power supply of the AK7604 with the power supply of the peripheral device turned
on. When using the I2C interface, pull-up resistors of SDA and SCL pins should be connected to
TVDD or less voltage.
WARNING: AKM assumes no responsibility for the usage beyond the conditions in the datasheet. 018011601-E-00-PB 2018/09
